Compact waste water treatment Ecodisk™

biological

Ecodisk™ is a wastewater treatment system based on a rotating biodisc system. This biological treatment technology is specifically designed to address the needs of hotels, construction areas, campings, military bases and any other small to medium sized facilities, particularly those in remote areas. It is also suitable for municipal wastewater generated in isolated zones that are not connected to main sewer systems. Ecodisk provides biological treatment for domestic wastewater within a range of 100 and 10,000 population equivalent (PE). Developed by PMT — a subsidiary of Veolia Water Technologies — this modular and compact biological treatment solution can be easily integrated into a wastewater treatment system. Upcoming wastewater can be fed through a simple pretreatment stage as screening before coming to the Ecodisk which serves as the main biological phase of the complete treatment. A minimal screening is suggested to remove big particles. Pretreatment can be enhanced with a process step such as grit and/or grease removal, primary settler or digester-settler. How Ecodisc works Ecodisk is a simple but efficient technology. Biodiscs are mounted on a shaft which is driven by a fixed speed motor. Discs are partially immersed in the effluent to be treated. The surface of the discs is then rotated (submerged and risen out of the wastewater). During the submersion phase, bacteria consume the pollutants such as carbon and nitrogen from the wastewater and then, once risen out of the water, the oxygen in air is consumed as a source to break down these pollutants.
